Registered 3rd and 4th degree tears are validated through manual assessment of patient records. We assume that especially higher degree tears may be diagnosed after trial assessment during repair. In order not to underestimate the level of higher degree tears, data on all 3rd and 4th degree tears in our study population registered in the hospital register during the trial period will be retrieved after the end of the trial. These data will be validated against patient records and any additional confirmed cases of 3rd and 4th degree tears in our study population will be incorporated into the final dataset.
